Hello,

I am trying to install elasticsearch 6.8.23 on Oracle Linux 8. I am using openjdk version "11.0.16.1".

I have this error at starting elasticsearch :  
Caused by: java.lang.IllegalArgumentException: none of the ciphers [TLS\_ECDHE\_RSA\_WITH\_AES\_256\_CBC\_SHA384, TLS\_ECDHE\_ECDSA\_WITH\_AES\_256\_CBC\_SHA384,  
TLS\_ECDHE\_ECDSA\_WITH\_AES\_256\_CBC\_SHA, TLS\_ECDHE\_RSA\_WITH\_AES\_256\_CBC\_SHA, TLS\_RSA\_WITH\_AES\_256\_CBC\_SHA256, TLS\_RSA\_WITH\_AES\_256\_CBC\_SHA, TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA256,  
TLS\_ECDHE\_ECDSA\_WITH\_AES\_128\_CBC\_SHA256, TLS\_ECDHE\_ECDSA\_WITH\_AES\_128\_CBC\_SHA, TLS\_ECDHE\_RSA\_WITH\_AES\_128\_CBC\_SHA, TLS\_RSA\_WITH\_AES\_128\_CBC\_SHA256, TLS\_RSA\_WITH\_AES\_128\_CBC\_SHA]  
are supported by this JVM

When I check support matrix, elasticsearch 6.8 should be running on Oracle Linux 8 with OpenJDK11 :

> **[Support Matrix](https://www.elastic.co/support/matrix)**

I also test with OpenJDK 1.8.0, same error.  
Is the support matrix up to date ? Maybe some configuration to adapt ?

Thanks for help
